Identified the issue with the background, will repackage and update for tommorow. (On holidays, limited ability to upload). Red squares? Never had that happen. Try uninstalling and reinstalling then restarting .. It may just be an error in unpacking. If that doesnt work please tell me what mods you are running, pr version, and if you have any custom kernels installed, then i can look into it.

also - ancelad, doesnt look like anyone has had issues with the postinst. Considering you dont even need root to run that script i cant imagine how it could be an issue
